Jordan Lyles hasn’t allowed more than two runs in a game since May 12. During his last three starts, the Astros righthander has given up just three runs in 21 combined innings while striking out 18 and walking only three. After improving to 4-1 overall this season with a team-leading 3.22 ERA, the 22-year-old discussed his repertoire Tuesday during a 10-1 victory against the Milwaukee Brewers at Minute Maid Park.

Lyles on his four-seam and two-seam fastballs: “When I need that ground ball, I’ll lean on the two-seamer. But maybe if I’m going low to rightys and I’m just trying to attack ‘em, I’ll give it my best four-seam fastball. Not trying to fall behind too many guys. The two-seamer’s got a little bit more movement, so there’s a little bit greater chance of it not going where you want to. So when it’s time to go after the batter, I’m definitely going to the four-seam.”

Using his slider for an out pitch, his curve being a little off and mixing in his changeup: “Yeah, definitely. The curveball wasn’t the same curveball as the last outing I had in Seattle. I knew that from the start. But I kept working on it and keep going to it when I needed it. I just wasn’t able to put guys away with it — I left up a lot of two-strike curveballs over the plate. But I think I threw a pretty good mix of pitches (Tuesday) — changeups, curveballs, sliders and cutters. Just doing whatever it takes to get someone out, I guess.”

Pitching with something to prove but also staying grounded: “It’s easy for me because I know where I was last year and two years ago. For me to just throw away what happened the past year, it’s not right. I know where I came from and I’m just trying to take it one day at a time right now.”
